Abstract

   This document defines new Modular Exponential (MODP) Groups for the
   Internet Key Exchange (IKE) protocol.  It documents the well known
   and used 1536 bit group 5, and also defines new 2048, 3072, 4096,
   6144, and 8192 bit Diffie-Hellman groups numbered starting at 14.
   The selection of the primes for theses groups follows the criteria
   established by Richard Schroeppel.
